Your short plan for this week

Do now

For every offered test, ask four things: what it looks for, how accurate it is, possible next steps and whether it is optional.

Coming up

Check whether you need a full bladder, whether a support person can attend, and how unexpected findings are communicated.

Pause and ask

Do not compare one scan measurement with an app illustration; clinicians interpret measurements together and in context.

What is happening

Baby’s development this week

Bones, facial structures and tiny movements are developing, although movement is not usually felt yet.

Plain-language examples

What this means in real life

An ultrasound due date may replace a last-period estimate when the measurements and clinical context support that change.

A short checklist

What to do now

  • For every offered test, ask four things: what it looks for, how accurate it is, possible next steps and whether it is optional.
  • Review medicines and supplements with a clinician or pharmacist.
  • Choose food-safety and substance-free habits without chasing perfection.

Ask what each screening test can and cannot tell you before deciding.

For the support person

One useful thing a partner can do

  • Take notes during the appointment if invited, then repeat back the plan so neither of you has to remember everything under stress.

Contact your care team

Contact your doctor or maternity team promptly

Some concerns need advice before the next routine appointment even when they do not feel like an emergency. If a symptom becomes severe, sudden or frightening, use urgent care instead.
